Explanation of how the FEP is treated

Excavation/operation: Neglected since expected effects will occur during Temperate period. Temperate: Generic modelling of effects on chemistry of fractures and changes of hydraulic conductivity in grouting boreholes. Periglacial: Not specifically handled. Extrapolation of results from Temperate period. Glacial: Not specifically handled. Extrapolation of results from Temperate period. Earthquakes: Not relevant.
